Calc phos fits the use of several languages, check it out, it fits also in the NM line.
I am not shure that this is mimicry, if she has learned those languages, but if she acts as a taperecorder, then its mimicry, and remedies fore that is:bell, cupr, hyosc, sars, stram, veratr. But that does not fit as a constitutional, in case there are several layers. A start treatment would then imply the use of agar, china, tuberculinum.
